The effects of tantalum addition on the microtexture and mechanical behaviour o...
Tejado, Elena; Carvalho, Patricia Almeida; Munoz, A.; Dias, Marta; Correia, J.B.; Mardolcar, U. V.; Pastor, Jose YgnacioTungsten (W) and its alloys are very promising materials for producing plasma-facing components (PFCs) in the fusion power reactors of the near future, even as a structural part in them. However, whereas the properties of pure tungsten are suitable for a PFC, its structural applications are still limited due to its low toughness, ductile to brittle transition temperature and recrystallization behaviour. Therefo...

Consolidation of W–Ta composites: hot isostatic pressing and spark and pulse pl...
Dias, Marta; Guerreiro, F.; Correia, J.B.; Galatanu, Andrei; Rosinski, M.; Monge, M. A.; Munoz, A.; Alves, E.; Almeida Carvalho, PatriciaComposites consisting of tantalum fiber/powder dispersed in a nanostructured W matrix have been consolidated by spark and pulse plasma sintering as well as by hot isostatic pressing. The microstructural observations revealed that the tungsten–tantalum fiber composites consolidated by hot isostatic pressing and pulse plasma sintering presented a continuous layer of Ta2O5 phase at the W/Ta interfaces, while the s...
A brief summary of the progress on the EFDA tungsten materials program
Rieth, M.; Dudarev, S. L.; Vicente, S. M. Gonzalez de; Aktaa, J.; Ahlgren, T.; Antusch, S.; Armstrong, D. E. J.; Balden, M.; Baluc, N.; Barthe, M. F.The long-term objective of the European Fusion Development Agreement (EFDA) fusion materials programme is to develop structural and armor materials in combination with the necessary production and fabrication technologies for reactor concepts beyond the International Thermonuclear Experimental Reactor. The programmatic roadmap is structured into four engineering research lines which comprise fabrication process...
